3. Overview of the Fight↑topThe encounter against Tsulong is a two-phase fight. The two phases, called the Night Phase and theDay Phase, alternate throughout the encounter, on a fixed timer.

During the Night Phase, Tsulong is hostile, and your raid must DPS him, while dealing with several of his abilities.

During the Day Phase, Tsulong is friendly, and your raid must heal him (much like the Valithria Dreamwalker encounter in Icecrown Citadel), while protecting him from various types of adds.

In order to defeat Tsulong, you must either bring him to zero health during a Night Phase, or tofull health during a Day Phase. Tsulong's health is reversed each time a phase change occurs, so that the amount of health that is missing from Tsulong's health in the Night Phase becomes the amount of health he has during the Day Phase. For example, if you DPS Tsulong down to 80% health in the first Night Phase, when he enters the Day Phase, he will have 20% health. If you then heal a further 20% of his health during this phase (bringing him up to 40% health), he will have 60% health when entering the Night Phase.When first engaged, Tsulong will be in the Night Phase, and every two minutes after that he will switch between phases. He has an energy bar that slowly fills up over time, and a phase transition occurs each time the bar is full. However, since the boss always gains energy at the same rate, and does not use his energy for anything, this has no implications for your raid and it is merely a means to tell how close the next transition is.4. Night Phase↑topThe Night Phase is the first phase that Tsulong will be in. The phase lasts for exactly 120 seconds, after which time he enters the Day Phase.4.1. AbilitiesDuring the Night Phase, Tsulong makes regular use of the following abilities.

Shadow Breath is a frontal cone breath attack that deals a high amount of Shadow damage and applies a stacking debuff to the affected targets, which increases Shadow damage taken by 100% for 30 seconds, per stack. This ability forces the use of two tanks.

Dread Shadows is a stacking debuff that Tsulong applies to all raid members every 2 seconds. Each application deals a moderate amount of Shadow damage, and increases the damage that the players take from Dread Shadows by 10%.

To counter-act the Dread Shadows debuff, Tsulong regularly creates a

Sunbeam at a random location (usually behind him). This is a large beam of light that removes the Dread Shadows debuff from any player who moves into it. However, each second that a player stays in the Sunbeam, its radius becomes smaller, until it eventually disappears.

Nightmares is a spell that Tsulong regularly casts at the location of a random player. It deals a large amount of Shadow damage to all players within 8 yards of the point of impact, and also fears them for 3 seconds. The fear effect can be dispelled. This ability does not appear to target melee players.

4.2. StrategyWe will begin by summarising the strategy for this phase, before going into more details.

Have Tsulong tanked facing away from the raid, and perform a tank-switch for every one of Tsulong's

Shadow Breaths. Make sure that the tank currently not tanking Tsulong is not in front of him.

Have the ranged DPS and healers spread out at least 8 yards apart, to minimise the damage and fears caused by

4.2.1. PositioningAs we mentioned, Tsulong should always be facing away from the rest of the raid, and no other players except the tank that is currently tanking him should be in front of the boss. This is important, since the boss'

Shadow Breath is extremely damaging.The rest of the raid should spread out in a semi-circle around the boss, making sure that everyone is at least 8 yards away from other players. This will help minimise the damage from

Shadow Breath with no stacks of the debuff applied by the breath itself. This means that a tank switch should take place after every breath attack cast by the boss.Even though we have mentioned it before, we will reiterate that it is very important that the tank currently not tanking Tsulong does not stand in front of him.4.2.3. Resetting Dread ShadowsA crucial aspect of this phase is making sure that everyone resets their

Dread Shadows debuff. Ideally, everyone should reset their debuffs before they exceed 15 or so stacks.When resetting the debuff by running into the

You will have to assign an order for players to reset their debuffs, and keep in mind that a Sunbeam will not last long enough to allow the entire raid to reset their debuff. It may also be possible (and sometimes preferable, maybe) to simply ensure that players have a means of tracking everyone's stacks of Dread Shadows on their raid frames, and that they just use common sense and on-the-fly assignments for resetting their stacks. In any case, this is something that pertains to the organization of the raid.Finally, tanks must also remember to reset their debuffs whenever they are not tanking Tsulong.5. Day Phase↑top2 minutes after the start of Phase One, Phase Two will begin. This phase lats for exactly 2 minutes, after which time Tsulong will once again begin.5.1. AbilitiesDuring Phase Two, Tsulong is friendly to your raid.

Sun Breath is a frontal cone breath attack that Tsulong regularly casts. It deals a very high amount of damage to any adds it hits. If it hits any raid members, it buffs them with

Make sure that the Embodied Terrors and the Fright Spawns are tanked in front of Tsulong whenever possible, so that he damages them with his breath.

Make sure that the Fright Spawns are always facing away from the raid.

5.2.1. Healing Tsulong and Other Healing ConcernsYour raid's main goal during this is phase is not only to survive, but also to heal Tsulong as much as possible. As we have explained before, any healing that you do to the boss during this phase is the same as damage done to him during the Night Phase, and contributes to your success in the encounter.Firstly, healers should always position themselves in front of Tsulong, so as to benefit from the

Bathed in Light buff granted by his breath attack. We will remind you that the breath attack does not damage raid members during this phase, and only damages adds. Also, Tsulong often turns around, meaning that he will not always face in the same direction, and the healers must be quick to adapt to the boss' new position.In addition to healing Tsulong, the healers will have to keep the rest of the raid alive. There are several sources of damage to note.

5.2.2. Dealing with the AddsYour tanks and DPS players' only concern during this phase is to kill the adds. This is extremely important, not only for your raid's survival, but also because it reduces the damage that Tsulong takes.Whenever an Embodied Terror spawns, the tank should pick it up and move it in front of Tsulong. If the boss breathes on the add, it will deal a lot of damage to it, making it much easier to kill. Your DPS players should focus on killing the Terror as quickly as possible.The Fright Spawns that appear when an Embodied Terror dies are very problematic. They must be killed through AoE damage very quickly by your raid, as the frontal cone attacks that they cast are very damaging and disruptive. These adds should also be tanked in front of Tsulong, but the tank must be careful that they are not facing towards the healers or other raid members present in that area.Untable Sha adds are the top priority, since they must be killed before they reach Tsulong, or else they deal a massive amount of damage to him. These adds cannot be tanked.There is no required coordination between your two tanks in this phase. Indeed, there only appears to be a need for one tank, so you will just have to decide which one of the tanks picks up the Embodied Terrors, and the resulting Fright Spawns.6. When to Use Heroism/Bloodlust/Time Warp↑topWe recommend using

Time Warp during a Night Phase. This is because there are fewer distractions for your raid in this phase than in the Day Phases, and we suspect that it is more efficient, in terms of progressing on defeating Tsulong, to DPS him rather than to heal him.7. Learning the Fight↑topYour raid will have to learn how to properly handle the mechanics in both of Tsulong's phases. Fortunately, since the phase transition happens purely based on time, it is possible just focus on getting through the Night Phase (at the cost of lower raid DPS) simply to experience the Day Phase.During the Night Phase, the most difficult aspect by far is proper usage of

Dread Shadows. This may take some practice, but once this aspect is mastered, the remaining abilities in this phase should be easy to handle.During the Day Phase, your raid will have to become accustomed to standing in the way of Tsulong's breath. Additionally, efficient killing of the Fright Spawns will probably prove to make the difference between success and failure in this phase. It is imperative that all players focus on killing these adds as soon as they spawn, to make the learning of the fight easier.We do not know what the enrage timer of the fight is, nor what the final tuning of the damage values of the abilities is like, but we expect that the fight will provide a considerable challenge in these regards.________________________"Une biffle c'est euh giffler une personne avec sa bite!!!
